SR520 Full Closure This Week-End

Here is information from WSDOT:

Reminder: Full SR 520 closure scheduled for Jan. 27-30

Last month, crews removed five of the eight lengthy girders that supported an old, now-retired westbound SR 520 off-ramp that extends over the highway near the Washington Park Arboretum. Crews plan to remove the three remaining girders later this month during a weekend closure of SR 520.

 All lanes and ramps of SR 520 between 92nd Avenue Northeast and Montlake Boulevard will close from:

• 11 p.m. Friday, Jan. 27, to 5 a.m. Monday, Jan. 30.

To ensure public safety that weekend, crews also will close the bicycle/pedestrian path on the new floating bridge and, on Saturday only, the Arboretum Waterfront Trail will be closed while crews work to rebuild the trail. 

Motorists will need to use I-90 or drive around Lake Washington if traveling between Seattle and the Eastside during the weekend highway closure.

Montlake-area closures

Before and during the weekend highway closure, crews on the SR 520 Montlake Phase project plan to inspect a sewer line that crosses SR 520 near Montlake Boulevard. The work will require 15- to 30-minute closures of Montlake’s westbound SR 520 on-ramp to unload equipment, along with a single right-lane closure on southbound Montlake Boulevard between the westbound and eastbound SR 520 on-ramps. These closures are scheduled from:

9 p.m. Wednesday, Jan. 25, to 5 a.m. Thursday, Jan. 26 9 p.m. Thursday, Jan. 26, to 5 a.m. Friday, Jan 27 11 p.m. Friday, Jan. 27, to 11 a.m. Saturday, Jan. 28 11 p.m. Saturday, Jan. 28, to 11 a.m. Sunday, Jan. 29 A temporary noise variance will be in place for this work and neighbors may hear a Vactor truck (pictured at right) used to inspect the sewer lines. During the hours listed above, crews also may close a left lane of southbound Montlake Boulevard between the Montlake Bridge and East Shelby Street. Sewer inspection and construction work is weather-dependent. If closure dates change, we will send updates through these emails.

Taking advantage of clear skies and just-above-freezing temperatures, crews towed the last of the old floating bridge’s 31 pontoons from Lake Washington last Saturday, Jan. 14. Like the 30 aged pontoons that preceded it, Pontoon N was towed through the Lake Washington Ship Canal before making its way through the Hiram M. Chittenden (Ballard) Locks. Pontoon N was then towed to Shilshole Bay and turned over to TrueNorth Operations Group, which bought all 31pontoons for use elsewhere as docks, artificial reefs, wharfs or other marine structures. Pontoon N was the 108th pontoon to pass through the locks since August 2012. That’s when the first of 77 new pontoons for the new, replacement floating bridge started to arrive from Aberdeen. Crews with the SR 520 Floating Bridge and Landings Project will continue with some minor marine work in coming months on Lake Washington, but the departure of Pontoon N marks a key milestone as decommissioning of the old floating bridge draws to a close.
